Please solve this computer science problem.
Create a program (or set of programs) which accomplish the following for each complex data type (list,tuple,set,frozenset, dictionary): create the item with at least 4 elements Append an element Remove an element Insert an element in the middle somewhere Append another array of the same data type Append another array of a different data type (for example, if you have a dictionary, append a set or tuples And do the following: Output the results after each step. Report and explain any errors (if a line of code generates an error, comment it out along with a comment on what the error was and your reasons for that error) Create a range of negative numbers Create a range of positive even numbers Insert a range into each data type that would allow it Please explain each error you ran into
QUESTION 7 1) Write a maxConsecutiveDiff function which returns the maximum difference between any two consecutive values in the array. Consecutive values are next to each other in an array (+/- 1 index) This function should accept all required data as parameters. Examples If the array is 17 15 16 11 14 the maximum consecutive difference is 5 which is the difference between 16 and 11. If the array is 10 13 11 12 19 the maximum consecutive difference is 7 which is the difference between 12 and 19.

3. Selection Sort• The idea in a selection sort is that you locate the largest item out of a set ofunsorted items, and move it into position at the end of the unsorted items. Asorted region grows one item at a time, while an unsorted region shrinks.• As done in Part 1, fill an array with random numbers.• Write a function that locates the largest element in the portion of the arraybeginning at the start of the array, up to a given index, and swaps the largestitem with the item at the given index.• E.g. If searching a[0] to a[7] locates the largest item at a[4], a[4] and a[7] would beswapped.• Write a second function that calls the first function repeatedly, until the entirearray is sorted. (Each time the first function is called, it will search one fewerelement)
Exercise - Collection Functions Using the code below, use the map function to create an array of Int values, whose values are equal to the original integer value, plus 1. Use $0 as you iterate through the values of the array. Print the resulting collection. 5 let testScores = [65, 80, 88, 90, 47] Using the code below, use the filter function to create a new array of String values. The new array should only include Strings longer than four characters. Use $0 as you iterate through the values of the array. Print the resulting collection. Olet schoolSubjects = ["Math" , "Computer Science", "Gym", "English", "Biology"] Using the code below, use the reduce function to subtract all of the values within the array from the starting value 100. Print the resulting value. let damageTaken = [25, 10, 15, 30, 20]
